中新网成都9月13日电 (记者贺劭清)记者13日从成都理工大学地灾防治与地质环境保护国家重点实验室获悉，雷达卫星遥感监测结果显示，此次地震导致贡嘎山主峰东侧海螺沟、磨子沟、燕子沟、南门关沟等冰川及其后缘山体均监测到较显著形变信号，主峰西侧冰川受地震影响相对较小。9月5日，四川泸定县发生6.8级地震。

B | Washington, Oct 11 (UNI) The Chinese economy will post the lowest GDP growth in four decades in the current year, barring performance during the initial COVID-19 crisis in 2020, the International Monetary Fund (IMF) said on Tuesday.

"The revisions reflect the downgrade for growth in China, to 3.2 percent in 2022 (the lowest growth in more than four decades, excluding the initial COVID-19 crisis in 2020). COVID-19 outbreaks and lockdowns in multiple localities, as well as the worsening property market crisis, have held back economic activity in China, " the IMF said in its World Economic Outlook.

However, China’s growth is expected to rise to 4.4 percent in 2023, the report added.

COVID-19-related lockdowns have taken a significant toll on China’s economy, particularly in the second quarter of 2022, according to the reports. Particularly, the property sector, which represents the fifth part of the nation’s economy is rapidly weakening, it added.

"A worsening of China’s property sector crisis could spill over to the domestic banking sector and weigh heavily on the country’s growth, with negative cross-border effects," the IMF said.
